To all 'whom it may concern:

Be it known that I, Gomma W. Fnonerate and of very simple, economicalconstruction.

\ My invention consists generally in locating a baiile wall within thespace inclosed by the drier, between which wall andl the outer wall ofthe drier a flue is provided leading to the exhaust or exit.

In the accompanying drawings forming part of this specification, Figure1 is a perspective view of a drier embodying my invention, Fig. 2 is avertical, longitudinal,

sectional view of the same, Fig. 3 is a detail.

view illustrating the manner of supporting the drier rack.

In the drawing, 2 represents the front wall of the drier, 3 the sidewalls, 4 the rear wall and 5 the top, inclosing a chamber or space 6.

7 represents a series of inverted T rails,

the horizontal flanges-of which form supports for the wheels 8 onhangers 9 to which the racks 10 are secured. These racks are equippedwith the usual rods 11 on which the garments to be dried are hlmg. Theracks have the usual face plates 12 closing the upper portion of thefront wall of the drier in the usual manner and the outer ends of therack supporting rails are provided with posts 12, of suitableconstruction. These rack supporting rails form substantial supports forthe rack hangers and permit the racks to be moved easily back and forthin the drier, even when `filled with clothes. Any other suitable form ofbar may be used in' .place of these T-bars, if preferred.

The lower portion of the wall 2 has a draft opening 13 and a door 1 4therefor, and in the lower portion of the chamber 6 I provide a radiator15 supported on bars 16 and connected with a suitable source of heat,such as steam or hotl water, preferably the former. In. the rear of theracks I provide an upright baille wall 17 extending parallel with therear wall 4 to a pointnear the top 5, a throat or passage 18 beingformed between said wall 17 and the top 5 leading to a diving flue 19that is formed between the walls 17 and 4, and extending transversely ofthe chamber 6, preferably from the top to the bottom thereof. The lowerportion of the chamber 6 has a pipe connection 19, extending preferablyout through the wall 3 and communicating with awaste or discharge pipe20. The outer end of the pipe 19 has aclean-out thimble 21 'capable ofremoval to obtain access to the pipe 19', and supply and return pipes 22and 23 are conduct-ed through the wall 3 of the drier to the radiator.

As indicated in Fie'. 2, a circulation of air will be establishedthrough the opening 13 and up through the radiator and the racks anddown the flue 19 to they exhaust pipe. The baffle wall will separate thedamp and heavy air from the fresh and heated air used in drying theclothes. Furthermore,

a suction will be established in the diving iue 19 which will hasten thecirculation of air through the chamber 6 and cause the currents of airto ow faster through and among the garments hanging therein withoutdrawing any of the fresh and heated air before it is ladenwith'moisture.

By regulating the size of the opening 13 the degree of the draft throughthe chamber can be modified as desired. Y v

I have shown a radiator coil located in the chamber 6,but do not confinemyself to this means of heating the chamber, as any other suitableapparatus may be used in place of it. v

In driers as 'generally constructed, the warm air, rising and passingbetween the clothes, becomes saturated with the moisture therefrom anddrops back to the lower portion of the drier, to be again heated-andlifted Vamong the clothes. This operation continues, the moisture -beingdried out of 'the air as it falls, but the soapy matter remaining insuspension and being deposited upon the clothes until, althoughthe moisture may be removed from the garments,

they will have a stiff, soapy feeling, which isL peculiarly incidentalto the drying of clothes in an ordinary drier. With my diving flueconstruction this objection is avoided. 'Ihe` warm air rises .among theclothes, gathers up thelmoisture therefrom and passing over thepartition wall drops down to the bottom of the iue 19 and passes outthrough the exhaust pipe, While a fresh supply' of air enters and isheated and discharged, among the clothes. The partition prevents thedescend ing currents of moisture laden air from owing back among thecoils of the radiator and rising again among'the clothes. The result' isthat when the arments are dried they will be soft and iiexible and thatgreasy, starchy feeling so often found in clothes dried in a laundrydrier,

will be entirely absent. The partition positively prevents the moistureladen air from returning to the heater and insures a rapid circulationlof the air through the drier.

I claim as my invention: A

1. A laundry drier comprising a casing having a heating chamber inclosedby said casing and a heating means therefor and an air inlet in itslower wall, a baille wall provided within said casing vand extendingvertically therein from the floor of said casing to apoint near the topthereof, saidbaiiieV wall being spaced from one of the upright 'walls ofsaid casing to form a descending ue, the space between the upper portionof said baffiewall and the topof said casing forming an inlet opening tosaid flue)drying racks arranged within said cham er between. said airinlet opening and the opening leading to saidV descending flue, saidheating means operatingV to heat the air entering saidinlet opening asit ascends with# said chamber and before it reaches said drying racks,said descendin I yiiie being closed at the bottom and provi ed in one ofits sidewalls with an exit opening extending outwardly through saidcasing, slib.-

stantiallyv as described.'

i ,2. A laundry ldrier comprising a, casing having a heating chamberandan' air inlet opening in its lower wall, drying .racks 1n the upperportion of saidchamber and heatling means interposed between said dryingracks and said air inlet opening, the cur.- rents of air from saidinlet. opening being compelled to circulate around -said heating meansbefore reaching said racks," said heat ing chamber having a verticallyarranged descending flue communicating with the upper portion of saidchamber, lthe heated air being com elledto pass through said racksbefore reac ing the inlet opening to said descending flue, the lowerwalls of said descending iiue having an exit opening andI a pipetherefor leading outside said casing, a circulation being established insaid chamber upwardly through sa-id racks and downwardly through saiddescending flue and throuohsaid exit opening to a point outside said'camber. y

In witness whereof, I have hereunto set my hand this 29th day of October1909.
